ADJUSTABLE LOCK STRIKE.

Application filed June 1,

To all whom it may concern:

Be it known that l, LEON O'rrINGER, a citizen of the United States, and resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Ad- 7 justable Lock Strikes, of which the following is aspecification.

This invention relates to an adjustable lock strike and more particularly, to articles of manufacture of that type adapted to be secured to door frames and with which the lock boltvcoacts toretain the door in its closed position.

It is the primary object and purpose of the present invention to provide a simple and inexpensive lock strike particularly designed for the purpose of facilitating the initial installation of a lock strike upon automobile bodies so as to eliminatethe necessity of cutting down or adjusting the door bumpers in order that the bolt member may properly coact with the strike. 1 also contemplate the provision of a lock strike which may be subsequently easily and quickly adjusted to compensate for sagging of the door, due to warping of its structure or of the frame, or other causes which would result in an improper coaction between the lock bolt and the strike when the door is closed so that the door would not be seecurely held in its closed position.

it is another object of my invention to provide an article of this character constructed in the form of a single casting and wherein provision is made for a series of adjustments. In each adjustment of the strike upon the door frame, the holding screw or other securing means is driven into the frame at a new place so that when the strike is fixed in its adjusted position, it held upon the door frame as when it is initially adjusted and attached thereto.

ln the accompanying drawings 1 have disclosed several practical constructions of the improved adjustable lock strike and it will he noted therefrom that in its generic aspect, the same fundamental thought is inherent in all of the illustrated constructions. Thus in each case I provide the lock strike with a slot adapted to receive a permanent fastening and guide screw threaded in the door frame and one or more additional screw receiving openings which are designed to receive additional screws to rigidly fix the Serial 1V0. 474,081.

lock strike in any one of several possible adjustments upon the door frame. I also propose to employ temporary plugs or closures by means of which the screw receiving openings not being used may be closed so that the lock strike will present a heater appearance.

with the above and other objects inview, the invention consists inthe improved lock strike and in the form, construction and arrangement of its several parts as will be hereinafter more fully described, illustrated in the accompanying drawings and subsequently incorporated in the subjoined claims.

In the drawings wherein l have illustrated several practical and desirable embodiments of the invention and in which similar reference characters designate corresponding parts throughout the several views,

Referring in detail to the drawings and more particularly to Figure 1 thereof, the lock strike as therein shown consists of a single one-piece metal casting having the body portion 5 substantially of rectangular form in plan, said body portion of this type of lock strike having the usual obliquely inclined striking face with which the end of the spring bolt of the door lock coacts until the end of the bolt is projected behind the end of the strike body 5.

Upon the end oil-the body portion 5 of the strike with which the lock bolt coacts there is formed at the base of said body, a longitudinally projecting lug 6 having a longitudinal slot 7 therein, the wall of said,

slot at the upper face of the lug having a continuous countersink 8.

In addition to the lug 6, ears 9 are formed on the strike body 5 in the same plane as the lug '6 and project from opposite sides of said body. Each of these ears is provided witha plurality of screw receiving openings 10. In the illustrated case each car has three of these screw receiving openings though it is obvious that a greater or less number of'these openings may be provided in accordance with the desired number of adjustments. ,The openingslO at the upper faces of the ears 9 are likewise provided with countersinks 1i. Y

In the use of the invention as shown in Figure l, the strike is initially applied to the door frame in approximately its correct position for the engagement of the lock bolt therewith, by engaginga screw through the slot 7 in the lug 6 and threading the same into the door frame until the tapering head of the screw exerts'suiiicient pressure upon the walls of the countersink 8 to retain the strike temporarily in position. After the door has been closed to see that the bolt properly engages with the inclined face of the strike, such adjustment as may be necessary is made by loosening the screw disposed through the slot 7 and then shifting the strike on the doorframe, or by merely tapping the strike with a hammer to shift the same in either direction without loosening the screw. Fastening screws are then inserted through one of the openings 10 in each of the ears or lugs 9 and threaded into the door frame until the screw heads are flush with the facesot the ears 9 while the screw extending through the slot 7 is also adjusted into tight clamping engagement on the lug ti. Thus the strike will be very rigidly fixed in its proper-adjusted posibody in the proper manner so as to securely hold the door in closed position, it is a relatively simple matter requiring but a few moments time in order to properly ad ust the strike upon the door frame sodas to remedy this condition. Thus the screws disposed through the openings 10 are first removed'anad the screw extending through the slot 7 is then loosened and the strike shifted on said screw which serves as a guide after which the screw is tightened against the edges of the slot 7 to retain the strike in its adjusted position while, the fastening screws are inserted through another of the openings 10 in each series'and threaded at a new place into the door-frame. Thus the strike will be held with as great security as before since the screws disposed through the openings 10 do not enter the same apertures in the door frame which they formerly occupied. In this particular embodiment of the invention as each ear or lug 9 is provided'with three openings, still another adjustment may be made in the same manner as just described, should it become necessary.

in Figure 1 of the drawings, 1 have shown an alternative of this embodiment of the device wherein the ears or lugs 9 are not provided with the screw receiving openings but the body 5 of the strike is provided with a single centrally located screw receiving opening 10 The first adjustment of the strike is made when the strike is initially applied. to the door frame by inserting the securing screw through the opening 10*- and driving the same into the frame after the strike has been adjusted on the guide screw extending through the slot 7 in the lug 6. If additional adjustment is required, the individual user may by means of a suitable drill readily provide any number of additional screw receiving openings through the ears or lugs 9 Figures 2- and 3 of the drawings show another embodiment of the invention wherein the ears or lugs 9 are omitted and only the laterally extending lug 6 is provided upon the larger end of the strike body 5*. l his lug is provided with a'longitudinal slot 7 while the body of the strike is centrally formed with a series of longitudinally spaced screw receiving openings 10 The 'manner of adjusting this form of the strike will be readily understood. Thus whenthe strike is first applied and adjusted upon the door frame, the securing screw is engaged through one of the openings .10 after the strike has been adjusted with respect to the guide screw extending through the slot 7, after which the two screws are'then tightened. Should adjustment subsequently be required. the fastening screw is removed, the ad ustment made and said screw then inser In Figure 7 I have illustrated the simplest form ofthe adjustable strike whereinthe lugs 9, as well as the lugs 6 are omitted and only a rectangular'body strike body has a slot 7 similar to the slot 7 in Figure 4 and in addition to said slota screw receiving opening 10 extends through the strike body in longitudinal alignment with the slot 7. In this construction, when the strike is first applied to the door frame, only the attaching screw engaged through the slot 7 is applied. The adjustment is then properly made and the securing screw inserted through the opening 10 and threaded into the frame whereby the strike is rigidly held in its adjusted position. lin this form of the device, if-desired, additional screw receiving openings may be drilled through the strike body as required. Should subsequent adjustment of the strike become necessary it may bemade in the same manner as above referred to in connection with Figure 1 of the drawings.

in Figure 8 T show another form of the strike wherein the body 5 has the slot 7 in its forward portion and opening 10 extending therethrough in line with said slot. Upon the larger end of the strike body the lug 6 is formed and is preferably of equal width, to the body 0 the strike. The surface of the lug 6 is likewise inclined similarly to the surface of the body 5 and normally, the bolt is adapted to ride over the .lug 6 and behind the end thereof.

However, in case the "door should not be fully closed, the shoulder at the juncture of the lu 6 with the body 5" provides a safety,

catch with which the bolt will engage to pre vent the opening of the door. The Mg 6 has edge and is provided on opposite sides with centrally located screw receiving opening 10, though it will be manifest that if desired, a greater number. of openings for the securing screw may be provided in this, lug- In this instance, as illustrated, two ad justments of the strike may be made.

Figure 9 illustrates another alternative form in-which the strike body 5 has the longitudinal slot '4" opening on, its forward a single the ears or lugs 9, in each of which a plurality of spaced screw receiving open ngs 10 are provided. As shown, three adjustmentsof the strike are provided for.

opening 1O extending 5 is employed. This u adjusted and secured upon the door frame the screw receiving In Figure 10, the strike body 5 in addition to the slot 7 has the screw receiving therethrough. "In this case, the strike body is likewise provided with ears or lugs 9 in each of which a single screw receiving opening 1O is formed. This arrangement of the screw receiving openings provides for two adjustments of the strike.

In Figure 11, I have shown an embodiment of the strike fixed upon the door frame and in which the strike body has the screw receiving slot and opening as in Figure 10,

the strike body 5*, while the ears or lugs 9- are each provided with spacedscrew receivng openings 10. When the strike is first the attaching and guide screw 11 is tightened against the walls of the longitudinal slot in the strike body after which the securing screw 12 is threaded into the door frame and adjusted into tight clamping engagement with the body 5 of the strike. The

ing a laterally disposed lug 6 projecting centrally from one of its longitudinal edges and with which the end of the lock bolt I initially engages as the bolt rides over the face of the strike plate and into the rec tangular opening it "formed therethrough.

The lug 6* on-the strike plate has a slot 7 formed therein while each end of said plate is provided with a screw receiving opening 10 The manner of attachmentand adj ustment of this type of, strike plate will be obvious from the foregoing description.

Tn Figure 13 of the drawing T have illustrated several types of closure plugs which maybe readily applied to the screw receiving openings .of any one of th'eforms of the strike above referred to, which are not 0ccupied by the securing screws. At the left hand side of -tlaisiigure T have shown said plug as consistin of a pin 15 having a tapered head. liis tapered head is enclosed within a sheet metal cap 16 which is formed on opposite sides with longitudinally extending arms 17. As indicated in the drawing, these arms extend through the screw receiving opening in engagement against the opposite sides thereof and normallyproject beyond the face of the strike. The ends of the arms are bent outwardly atright angles and seated in an annular recess 18 formed in the face of the strike lil') strike.

At the right hand side of Figure 13, l have shown the detachable closure plug in the form of a rivet 19 having a split shank the portions or which are adapted to be outwardly bent and seated in the recessed face of the strike.

Figure lei represents an end View of the closure plug seen at the left of Figure l3 while Figure 15 is a similar view of the plug shown at the right of Figure 13.

In Figure 16 l have illustrated another form of this plug which. likewise consists oi a rivet or pin 21 having a tapering head corresponding with the countersink at one end of the screw receiving opening. l pon the periphery of said pin at its other end, a radially projecting lug 22 is formed and when the plug is inserted in the opening this lug moves through a groove formed in one side of said opening. After inserting the plug through the opening, said plug is then turned so as to position the lug thereon in the annular recess 2% out of registering relation with the groove 28. l hen the strike is applied with this form of detachable closure for-the screw receiv'lpng openings, when the screws are adjusted to tightly clamp the strike in a llXGtl position on the door frame, the bearing pressure of the ends of the plugs 21 against the frame prevents the casual turning movement of said plugs so that there is no possibility that the lugs 22 will align with the grooves 23 and result in the displacement or loss of said plugs.

in Figure 17 I show another form of the closure plug-which consists merely in the provision of a pin 25 of but slightly greater length than the length of the screw receiv.

ing opening and having a conical head 26,

at one of its ends, said pin projectingfrom the apex of thehead 26. Plugs of this type can be easily and quickly applied by simply centering the pin 25 through the screw receiving opening and then driving the same with a hammer until the head 26 fits snugly within the countersink at-the end of the opening. Witheach type of the closure plug herein referred to, when said plug is in position, the head thereof is flush with the surface of the strike so that the appearance of the strike is not detracted from by the exposed openings, while at the same time by the provision of these closures, the collection of dust and dirt within said screw receiving openings is obviated.

From the foregoing description considered in connection with the accompanying drawings, it will be seen that the present invenraanoeo tion provides a very simple and inexpensive lock strike whereby a plurality of adj ustments of the strike upon the door frame may be easily and quickly made should such adjustment become necessary owing to the sagging oi the door or warping of the door or its frame so that the spring ressed lock bolt does not properly coact wit the strike when the door is closed. The improved adjustable lock strike greatly facilitates the proper application of the same, especially when used upon automobile bodies and en ables the door lockto be initially applied so as to insure proper coaction of the lock bolt with the strike without necessitating the cutting down or the adjustment of the door bumpers, usually consisting of rubber stop plugs suitably fixed in the door frame.

While the device is primarily designed for use in connection with automobile door looks, it is apparent that it may also be advantageously employed in connection with ordinary house doors or in various other analogous instances where a quickly adjustable lock strike is desirable.

While I have herein described and illustrated numerous practical forms of the adjustable strike, it is possible to devise still further alternative structures which would accomplish the same end or purpose. It is accordingly to be understood that still further embodiments may be resorted to and I, therefore, reserve the privilege of adopting all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.
